목적: Cauliflower ear, characterized by thickening, irregular projection of the anterior ear and distortion of the auricular outline, is the result of bleeding or abscess between the perichondrium and the cartilage, followed by scarring and regeneration of cartilage from the perichondrium. Surgical correction of an established cauliflower ear is one of the most challenging problems in ear reconstruction. However, only a few reports have clarified the dissection of an established cauliflower ear in detail. Here the authors present cases of cauliflower ear that were treated using various techniques, and analyze the treatment outcomes. 방법:Seven cauliflower patients underwent surgery to restore normal contour of the auricle. Cosmetic results, patients satisfaction, ease of technique and the occurrence of the complication were analyzed. 결과:Patients age ranged from 25 to 52 years and the mean age was 34. All of the cases occurred unilaterally. Four cases were due to the perichondritis with abscess, and the remaining three cases were due to chronic irritating trauma. Five cases underwent sculpturing of the distorted cartilage with an addition of conchal cartilage to enhance the helical contour. In two cases we reconstructed the helix using the costal or nasal septal cartilage. One case developed otohematoma at two weeks after the surgery. 결론:The appropriate reconstructive technique for the treatment of cauliflower ear must be carefully selected according to the cause, type and degree of deformity and the availability of donor tissue.
